Chapter Text

The laboratory smells like ozone and failure.

Elena Urbica—Astgenne, she reminds herself, though the name still feels like borrowed clothes—stands at her workstation and watches her latest attempt at synthesizing a stable energy lattice collapse into itself. Again. The crystalline structure she'd been nurturing for three weeks dissolves in a cascade of light, each photon a tiny eulogy for wasted time.

"Shit," she says, to no one in particular.

The Rhodes Island workshop is empty at this hour. Most sensible people are asleep. Elena hasn't been sensible since she was nineteen and decided her family's generations of astrological tradition mattered less than the truth she could see in circuit diagrams and energy flows.

She pulls off her safety goggles and rubs her eyes. The numbers are still there when she closes them—equations dancing in the dark, mocking her. Energy doesn't just disappear, she knows this. There's a leak somewhere in her calculations, some fundamental incompatibility she hasn't accounted for.

Like mixing water and sodium. Beautiful, violent, and completely predictable in its destruction if she can manage to create a proper equation.

Her communicator buzzes. She knows who it is before she checks.

Elena’s eyebrow twitches. Of course Dorothy is awake. Dorothy is always awake. Last week Elena found her passed out at her desk, surrounded by half-finished calculations and cold coffee. The week before that, she'd had to physically confiscate an entire box of agrypnotics.

Not that Elena is in any position to lecture about self-care.

Elena looks at her workstation—scattered tools, a failed crystal, equations that lead nowhere. She should stay. She should figure this out. That's what Ferdinand would have expected. That's what her parents would have expected.

That's what she expects of herself.

But Dorothy offered tea, and Elena has never been good at saying no to Dorothy.

Dorothy's quarters are noticeably messier than Elena is used to—meticulous chaos, if such a thing exists. Every surface was covered with papers, equipment, half-disassembled devices that Dorothy had promised she'd "fix later." She insisted there was some secret system to it, some internal logic that made perfect sense if you only tilted your head and squinted, but Elena wasn’t so sure.

Nonetheless, Elena found it comforting, somehow. Like maybe chaos doesn't have to be failure. Maybe it's just... complexity waiting to be understood.

"Sit," Dorothy says, already moving through the small kitchenette with practiced efficiency. She's wearing an oversized sweater that definitely belongs to someone else—probably Silence, based on the feather-patterned sleeves—and her hair is escaping from its usual careful arrangement. Her tail sways absently as she works, and Elena catches herself watching the movement.

Stop it, she tells herself. You're here for help with your synthesis, not to stare at your colleague like some lovesick undergraduate.

"I brought the notes," Elena says, dropping her tablet on the least-cluttered section of the table. "Fair warning: they're a disaster."

"Mine always are too." Dorothy sets down two cups of tea—something herbal that smells like it might actually help Elena sleep, if she were actually capable of such miraculous things. "Show me."

Elena pulls up her calculations. They spread across the tablet's screen in layers, each iteration another failed attempt to force incompatible elements into harmony. "It's a three-way energy coupling." She explains. "Originium-based power source, conductive medium, and stabilizing matrix. Individually, each component works perfectly. But together..."

"They reject each other." Dorothy finishes, already tracing patterns in the equations with one finger. Her eyes have that particular brightness they get when she's working through a problem—like she's seeing something no one else can. "The resonance frequencies are all wrong. You're trying to make them vibrate in sync, but..."

"But they're fundamentally incompatible." Elena says. The words taste bitter. "Different base structures, different energy signatures. Like trying to mix oil and water."

Dorothy is quiet for a moment, still studying the data. Then she smiles—soft, almost sad. "You know, that's not quite true. About oil and water."

"What do you mean?"

"They can mix. You just need an emulsifier—something that can bridge the gap between them. A molecule with parts that love water and parts that love oil." Dorothy looks up, meeting Elena's eyes. "You're not looking for synchronization. You're looking for translation."

The concept hits Elena like a voltage spike. Of course. Of course. She's been trying to force the components into identical frequencies when she should have been finding the harmonics—the places where different vibrations could create something new instead of destroying each other.

"You're brilliant." Elena breathes.

Dorothy's ears flick—embarrassment, pleasure, something Elena can't quite parse. "I just know a lot about things that don't naturally fit together."

There's something in her voice that makes Elena look up sharply. Dorothy is smiling, but it's that particular smile she uses when she's thinking about her mother, about Pioneers, about all the people she couldn't save. The smile that means she's including herself in the category of broken things.

"Dorothy—"

"It's late." Dorothy says, already moving to clean up the tea cups. "You should go get some sleep. Your synthesis will still be there tomorrow."

It's a dismissal. A gentle one, but unmistakable. Elena knows better than to push—Dorothy has walls built from kindness, and they're harder to breach than any fortress.

As Elena gathers her tablet and heads for the door, Dorothy calls out: "Elena?"

She turns. Dorothy is backlit by the warm light of her quarters, tail curled around her legs, looking small and tired and impossibly beautiful.

"Thank you." Dorothy says. "For caring enough to keep trying. Even when things don't want to fit together."

Elena doesn't know if they're still talking about the synthesis.

"That's what science is." She manages. "Finding ways to make the impossible work."

Dorothy's smile goes softer. "Yes. I suppose it is."

Back in her own quarters, Elena pulls up her calculations again. She can see it now—the places where Dorothy's insight applies, where she can introduce harmonizing elements instead of forcing direct connections. It's elegant. It's beautiful.

It's exactly the kind of solution Dorothy would find, because Dorothy has spent her entire life trying to bridge impossible gaps between people.

Elena's hand hovers over the communicator.

Elena stares at that last message longer than she should. She thinks about emulsifiers. About molecules designed to bridge incompatible substances. About how sometimes the only way to make things work is to fundamentally change your approach. She thinks about Dorothy, wearing someone else's sweater in the middle of the night, solving problems that aren't her own because she can't help but try to fix everything. She thinks about oil and water, and the specific chemical miracle required to bring them together.

She puts her communicator aside and gets to work.

Not her synthesis—that can wait until morning.

This other equation—this strange new variable that makes her heart rate increase by approximately 18% whenever Dorothy smiles—that one might take significantly longer to solve.

Observations, Day One:

Subject: Elena Urbica (codename Astgenne)

Hypothesis: I have developed feelings of romantic attraction toward my colleague Dorothy Franks.

Evidence:
- Elevated pulse when in proximity to subject
- Difficulty maintaining professional boundaries
- Persistent intrusive thoughts about subject's wellbeing
- Desire to spend increasing amounts of time in subject's presence

Conclusion: This is inadvisable.

Further conclusion: I'm going to do it anyway.

Note to self: Delete this file before anyone sees it.

Second note to self: Don’t write lab notes about your love life, you absolute idiot.

Elena saves the file, encrypts it, and tries very hard not to think about what her sister would say if she knew.
